Operating Systems AIX Assigning Domain Server Breaks rlogin Post 302636395 by bakunin on Monday 7th of May 2012 11:07:17 AM

First off, the IP network you use looks fishy: the "usual" setup is to have a private network and routing to the internet shut off. Then, via a proxy server in a DMZ, selected systems are allowed to access the internet. To hide the (not-routable) private addresses from the internet usually NAT is used.

This works because several addresses of the IP address range are set aside and defined as a) not being routable and b) used for private purposes. This means, the normal property of an IP address to be distinct worldwide is not the case with these addresses. Everybody can use them (instead of having to registering them with the IANA), but in return you cannot access the internet with these.

The address ranges in question are (see RFC 1597 or RFC 1918, "Address Allocation for Private Internets"):

10 (-> one class-A net)
172.16 - 172.31 (-> 16 class-B nets)
192.168.0 - 192.168.255 (-> 256 class-C nets)

I presume you (metaphorical - maybe your predecessor admin) wanted to set up a private network, but mixed up addresses. Right now you are using official internet addresses, probably without having them registered and them being duplicate. This works well as long as there is absolutely no connection to the internet, but once there is (and you say that there is now) this will lead to errors galore.

I still cannot tell you why your specific error message showed up, but i suggest that you correct the most obvious error first, which will definitely prevent successful operation anyway.

I hope this helps.

rlogin(1c)																rlogin(1c)

Name
       rlogin - remote login

Syntax
       rlogin rhost [-ec] [-8] [-L] [-l username]
       rhost [-ec] [-8] [-L] [-l username]

Description
       The command connects your terminal on the current local host system, lhost, to the remote host system, rhost.

       Each  host  has	a  file  which contains a list of rhosts with which it shares account names.  The host names must be the standard names as
       described in When you use the command to login as the same user on an equivalent host, you do not need to specify a password.

       You can also have a private equivalence list in a file .rhosts in your login directory.	Each line in this file should  contain	the  rhost
       name and a username separated by a space, giving additional cases where logins without passwords are permitted.	If the originating user is
       not equivalent to the remote user, then the remote system prompts for a login and password as in

       To avoid security problems, the .rhosts file must be owned by either the remote user or root and it may not be a symbolic link.

       Your remote terminal type is the same as your local terminal type, which is specified  by  your	environment  TERM  variable.   Except  for
       delays,	all  echoing takes place at the remote site so the rlogin is transparent.  Flow control by and <CTRL/Q>, and flushing of input and
       output on interrupts are handled properly.  The optional argument -8 allows an eight-bit input data path at all times.	Otherwise,  parity
       bits are stripped except when the remote site's stop and start characters are other than and <CTRL/Q>.  A tilde followed by a dot (~.) on a
       separate line disconnects from the remote host, where the tilde (~) is the escape character.  Similarly, a tilde followed  by  <CTRL/Z>	(~
       <CTRL/Z>), where is the suspend character, suspends the rlogin session.

       Substitution  of  the  delayed-suspend  character,  which  is normally <CTRL/Y>, for the suspend character suspends the send portion of the
       rlogin, but allows output from the remote system.  A different escape character may be specified by the -e option.  There is no space sepa-
       rating this option flag and the argument character.

Options
       -8		   Allows an 8-bit input data path at all times.

       -ec		   Uses the specified character as the escape character.  If not specified, uses a tilde (~).

       -l username	   Logs you in as the specified user, not as your user login name.

       -L		   Runs session in litout mode.

Files
       /usr/hosts/*	   for rhost version of the command
